PUMP.

SPECIFICATION forming part of Letters Patent No.318,018. dated May 19, 1885.

Application filed February 6, 1885.

.To all whom t may concern,.- l

Be it known that I, ALONZO PALMER, a citizen of the United States, residing at Three Rivers, in the county of St. Joseph and State of Michigan, have invented a new and useful Improvement in Pumps, of which the following is a specification, reference "bei ng had to the accompanying drawings.

My invention relates to an improvement in pumps; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of a pump that embodies my invention. Fig. 2 is a vertical sectional view of the same, taken at right angles to Fig. l.

A represents a cylinder, from the lower end oi" which depends a suction-pipe, B. An inwardly-opening valve, C, is secured in the bottom of the cylinder A, and from the upper side of said cylinder extends the pipe D. A vertical pipe, E, extends in a line with the pipe D, and the ends of the said pipes are supported at a suitable distance from each other by the yoke F.

G represents a cylinder, which is open at both ends and provided with a valved opening, g, at its center. The upper portion, g', of this cylinder is of much smaller diameter than the lower portion, 9"'. rIhe lower end ot' the pipe E is provided with packing at e,

for working in the upper portion of the cyll inder, and the upper end ofthe pipe D is provided with packing d, for working in the lower portion ofthe cylinder. y

g represents a bail, that depends from the central head of the cylinder G, and to this bail is secured the upper end of a rod, H, the lower end of which is provided with an inwardly opening valved plunger, l1,v which works in the cylinder A.

To the upper end of the pipe E is secured the lower end of a pipe, I, which has a discharge spout, i, and which has at its upper end a bearing, i. Astandard, K, is secured to the pipe I at its lower end, extends vertically parallel with the pipe I, and at its upper end is provided with a bearing, k. The cylinder G is adapted to play vertically upon (No model.)

the pipes D E, and for this purpose is provided with trunnions g* on opposite sides, which bear in the sides 4of the divided lever L. One end of the lever L has pivoted to it the lower end [of a rod, M, as at m, and the upper end of the rod M is pivoted, as at m', between ears that project from the pipe E. A handle, N, is fulcrumedbetween the bearings t" and k, and is connected by a rod, O, with the free end ofthe lever L.

The operation of my invention is as fot lows: An upward movement of the cylinder G and plunger h fills the cylinder A and the lower portion of the cylinder G with water, and forces the water contained in the upper portion of the cylinder upward through the discharge pipe and spout. Downward movenient of the cylinderG and plunger h closes the valve C, and the water in the lower portion of the cylinder is forced into the upper portion thereof, which being smaller than the lower section, a'portion of the water is forced up and discharged through the spout. It will thus be understood that water is dis charged by both the upward and downward movement of the cylinder, and a continuous iowof `waterthroughfthejdischarge-spout is secured. A pump thus constructed is a combined force and suction pump',and is adapt-ed for use in wells of any depth, and for forcing water through hose, and for other purposes for which a constantandstrong How of water is necessary. A

Having thus described my invention, I claim--T l. The movable cylinder composed oi' scctions ofunequal diameters,in combination with pipes having packings for fitting in the sections ot the cylinder, a stationary cylinder secured to the lower end of oneof the pipes,and` a valved plunger which operates in the stationary cylinder, and which is connected to the movable cylinder,and is operated thereby, substantially as described.

2. The combination of the cylinder A, having valve C, pipe D, cylinder' G, having an upper and a lower section, the lower one of which is of greaterldiameterjthan2the upper section, packing on the pipe D, for working in the lower section, valve gin the said cylinder, a plunger, l1., that operates in the cylinder A,

IOO

and is Connected to and operated by the eylmy own I havehereto affixed my signature in inder G, `pipe E, hav-ing a packing ab its loW- presence of two witnesses. er end for Working in the upper section of the cylinder G, and a crank handle or lever for ALONZO PALMER" 5 operating the cylinder G, Substantially as de Vitnesses:
